I work in a small (3 people) team and we need to be able to share our calendar i.e. to see periods when we are busy/free perhaps to organise meetings and so on.

Outlook and Exchange is not an option.

I know about Google Calendar but I would prefer a tool we can host on our server (preferably PHP + MySQL).

Any suggestions?

I recommend Knutsen's WebCalendar - I've been using it for years. It's all PHP & MYSQL; completely open source. It's completely configurable. Everyone I've suggested to has adopted it.

I've done a lot of research for my own uses, and I revisit the options every now and then. What I've found is most of the calendaring solutions out there are actually pretty awful. It turns out that shared calendaring is really hard.

I originally went with Google Calendar, and I much prefer it. Now I use Google Apps since I got a domain. I like that it is hosted for me so I don't have to deal with the administration of the software and the service. Sure, it might be down sometimes, but I'm getting the service for "free" (advertising and information selling aside :-)). I know of a lot of tech companies with the manpower to setup/build their own solutions that use Google Apps because outsourcing the maintenance to Google frees up their IT staff to add more value.

That said, Zimbra includes a calendaring option in addition to providing email. I would stay away from Microsoft's products and their high priced per-client access, same with any of the large commercial offerings.

Like the overhead to solve server errors? ;-) thenextweb.com/2009/11/10/google-apps-calendars –  Arjan Nov 10 '09 at 16:10
    
I'm ok with google apps but for Zimbra it's no use, thunderbird with extensions or with sunbird does the same almost ... –  zillion Nov 10 '09 at 16:15
    
@zillion, how can Sunbird, or any add-on in Thunderbird, do any calendar things without a server that actually keeps the calendar items? A clients needs a server, I guess. –  Arjan Nov 10 '09 at 16:42
    
I just compare a little, I have checked a lot "for months" before choosing my own solution ... –  zillion Nov 10 '09 at 16:48
    
@zillion Sure, I also researched for months and settled on Google Calendar shortly after it was released, and switched to Google Apps when I got my own domain. I've been happy with Google ever since. –  jtimberman Nov 10 '09 at 16:58

Check out OpenGoo - Its kinda like Google Apps, but you can host it yourself. While its not quite comparable to Google Apps, it does meet your requirement of something you can host yourself.


2012-06-05 Update: Since I'd last posted this OpenGoo has changed their setup and project name. They're now Feng Office, and they've now buried the "host your own" option waaaaayyyyy down on the "Open Source" page. You can still host your own, just like before. The options and interface are a little better, but I've long since moved on to other options so I don't know how well the new version works in practice.

Just clarifying since I've been getting some down-votes for "incorrect" information... that was correct when I'd originally posted.

Not that I mind the down-vote, but why? –  AnonJr Nov 12 '09 at 16:18
    
Maybe because you've mentioned Google? ;) +1 because I'd also suggest OpenGoo. –  Bobby Nov 13 '09 at 14:13

The open standard for calendaring is CalDAV (RFC4791). Hopefully you can find a server and client to suit you (also see DAViCal server's client list).

Mostly for macs so it's not a good solution for everyone on any operating system ... (Windows,Mac,Linux,Bsd,Solaris - at least) But I clearly accept that his question is hard and answer it is far more difficult ... –  zillion Nov 10 '09 at 16:18

Apples CalDAV server (Darwin Calendar Server), written in pyhton is cross platform and open source. You can easily find documentation how to install it on your prefered OS on the web. –  Ludwig Weinzierl Nov 10 '09 at 18:01

Hi
I also develop apps in php/mysql I've been checking the answers posted here, and have found another alternative

You could get webcalendar php app, which exports calendar items to RSS http://www.k5n.us/webcalendar.php

Then, you could get the provider addon for thunderbird, that will allow you to import rss calendars (It works originally with Google Calendar) or you could just add the calendar rss feed to thunderbird rss feed reader

But then you'd need to invite all team members to your holidays? The fun of that aside, I doubt Doodle is easily used for that? –  Arjan Nov 10 '09 at 7:57

Do you need email integration?

If not, and you're just after a lightweight PHP app that lets everyone manage the calendar through a browser, then the following might fit the bill:

On the other hand if you do need to integrate with email, you will most likely need to use a CalDAV or iCal calendar server.

DAViCal will work with Mozilla, Evolution, Chandler, iCal and iPhone.

Another alternative might be to take a look at some broader CRM packages, as many of these incorporate calendar servers. This would be a wasteful approach if you have no intention of using any of the other features, but if you'd get any mileage out of any other CRM'y stuff (contact management, activity management, issue tracking, time tracking, inventory management, etc) then it could work for you. Sugar CRM seems to be the market leader and is PHP based though I'd recommend taking a look at OpenCRX.

+1 for mentioning DAViCal, it does fit the requirements when used with Mozilla Sunbird. –  codehead Nov 14 '09 at 9:32
